When Rosa heard Xander's words, a look of disappointment appeared on her face.
Seeing Rosa's disappointment, Xander suppressed his internal anxiety and said, "You're still a demon. Though you've rid yourself of Muzan's curse, you still need to drink blood."
Upon hearing Xander's words, Rosa nodded and replied, "Master, you're right, but you don't allow me to harm humans. I can drink the blood of wild beasts. It doesn't matter."
Xander smiled with satisfaction and said, "Come here."
Hearing this, Rosa approached Xander, looked up at him, and asked, "What happened, Master?"
Xander's hair gradually turned white, and his eyes became icy blue. Then he cut his finger and whispered, "Open your mouth."
Seeing Xander's actions, Rosa asked in surprise, "Master, what are you doing?"
Xander replied impatiently, "Why do you ask so many questions? Hurry up."
Upon hearing this, Rosa looked at the blood on Xander's finger. Although instinct made her feel a slight excitement, questions still lingered in her heart.
"Master, are you going to give me your blood?"
Xander nodded and said, "I once gave my blood to a little girl, and she gained the same abilities I have. I want to see if it's because of my blood."
Hearing what Xander said, Rosa was surprised again.
"Master, are you telling the truth?"
Xander smiled disdainfully and said, "Do I need to lie to you? Besides, if you don't hurry up, my wound will heal."
Saying this, Xander nudged Rosa, "Then forgive me, Master."
Hearing this, Rosa bowed her head in apology, then took Xander's hand with both of hers and finally wrapped her lips around his bleeding finger.
Xander didn't expect Rosa to act so directly and couldn't help but think, "This is warm and quite pleasant."
Then Xander felt the pull as the blood was slowly being drawn. When he sensed that about 100-200 milliliters had been absorbed, Xander said, "Alright, that's enough."
Upon hearing Xander's words, Rosa reluctantly opened her mouth and licked her lips before releasing Xander's fingers.
"Master's blood is cold and refreshing, with a light fragrance, very tasty."
Hearing this, Xander slapped Rosa on the head hard.
"Who asked you that!"
Rosa covered her head and said with a hint of grievance, "I don't feel anything else."
Hearing this response, Xander grasped his chin in confusion.
"Could I have been wrong? But it shouldn't be! Something must have gone wrong!"
Then Xander looked at Rosa and said, "Alright, it's late already, and dawn is approaching. I'll give you a task to complete."
When Rosa heard about the task, she sat down in front of Xander and asked, "Master, what task?"
Xander slowly said, "From now on, if you see demons harming people, kill them all. If you encounter someone from the Demon Slayer Corps, help if you can. If you meet a strong member of the Demon Slayer Corps, just run away. Understood?
Hearing this, Rosa nodded and said, "Rosa understands."
Seeing this, Xander turned and headed for the door of the small shabby hut, and all the web threads were instantly gathered by Rosa.
"Remember, your life belongs to me, no matter if you're a demon or someone else, no one can take it away."
Xander turned and said this, then left the small shabby hut.
Rosa stood in the shabby hut, watching Xander's back as he walked away, and a beautiful smile appeared on her face.
Suddenly, Rosa felt the blood in her body gradually becoming colder, and she felt a slight drowsiness.
"Truly the blood of the master. I just absorbed a little, and I already feel my body getting a bit cold, and this blood seems to be corroding my body."
Rosa staggered out of the shabby hut, clutching her lower abdomen. Seeing the light emanating from the horizon, she realized that dawn was approaching.
Seeing this, Rosa rushed into the mountains and forests, found a cave, and completely blocked the entrance with webs and stones. At this time, a layer of frost formed on Rosa's face.
After doing all this, Rosa lay down on the ground and fell asleep.
On the other end, Xander felt that the web pattern on his hand had become a little colder, and there were no more sensations.
Passing through a small village, then through a large forest, and climbing a mountain, Xander returned to the Butterfly Mansion.
Entering the courtyard of the Butterfly Mansion, Xander opened his mental perception and quickly located Shinobu Butterfly.
Coming to the medical room of the Butterfly Mansion, Xander saw Shinobu Butterfly flipping through records and then picking up a cup of water infused with blooming acacia.
Xander grabbed Shinobu Butterfly's mug and poured it out directly, then said, "Don't drink this in the future."
Shinobu Butterfly looked at Xander and gave a slight smile.
"Xander, you're back. This mission seemed very easy."
Xander said, "As long as I'm here, you shouldn't use such things anymore. Trust me, okay?"
Hearing this, Kocho Shinobu calmed down, looked into Xander's eyes, and slowly said, "I know you want to help me and even developed the Breath of Ice, but I still want to take revenge myself."
Xander gently smiled and said, "Well, since you're good at developing medicines, I have something nice for you."
With that, Xander reached into his pocket and took out four vials of potion from the spatial ring, pretending to pull them from his pocket and placed them in front of Kocho Shinobu.
"I accidentally found these four potion bottles. These potions can enhance the functions of the human body. You should study their composition, see if you can recreate them."
Coco Shinobu picked up one of the potion bottles, looked at Xander and said, "Have you tried all these things?"
Xander nodded and said, "Of course."
Then Xander explained to Kocho Shinobu what they were intended for.
Kocho Shinobu was so surprised that she opened her mouth wide.
Seeing Kocho Shinobu's surprised expression, Xander said, "If you don't believe me, you can try one of the bottles."
Hearing this, Kocho Shinobu opened a bottle of potion and drank it.
As time went on, Kocho Shinobu felt her body fill with strength, which meant that Kocho Shinobu had just consumed a potion that increased her strength.
She immediately challenged Xander to an arm-wrestling match. Although she lost, Coco Shinobu truly felt her strength increase.
"Amazing! My strength has almost doubled. If it's used by Gyome, the effect will be even more pronounced."
Hearing what Kocho Shinobu said, Xander felt a sense of pride.
"Of course, the System must be the best!"
Kocho Shinobu couldn't resist taking the other potions to test them. She discovered that her physical strength and speed also made a qualitative leap, and even her mind worked faster. Learning the results, Kocho Shinobu looked at Xander with shining eyes and said, "Xander, I don't know if you have more of these potions."
Xander smiled slightly and took out four more bottles of potion, one of each kind.
"These are the last four bottles. If you want more, there won't be any."
